After looking around at what the other *BSD's do for their $xxxBSD$ tags,

take the easy way out and implement the beginnings of something similar.
Don't worry, the code here is *dormant* so far, some "help" from cvs is
required.  This is going in now so that jdp can see what I'm working on.
This is an extension of the previous existing skeleton $FreeBSD$ code.
